What is Double Worm Slewing Drive WED21?

The Double Worm Slewing Drive WED21 is a high-performance rotational drive system engineered to provide robust torque transmission and reliable rotational motion for heavy-duty applications. This drive system integrates a double worm gear configuration, where two worms simultaneously drive the worm wheel, resulting in superior torque output and enhanced holding torque capabilities. Designed for heavy machinery and complex systems that require precision, durability, and high load-bearing capacity, the WED21 is an ideal solution for industries such as construction, mining, renewable energy, marine, and industrial automation.

The WED21 slewing drive is specifically designed to offer increased output torque, axial and radial load capacity, and tilting moment torque, making it suitable for demanding applications that require high reliability under harsh operating conditions. Whether used in turntables, cranes, or any other heavy machinery requiring precise rotational movement, the WED21 provides powerful performance without sacrificing efficiency or durability.

This drive system features a self-locking function, preventing unwanted movement when the drive loses power, ensuring safety during operation. Furthermore, the WED21's high-quality construction, including its sealed casing and heavy-duty bearings, ensures longevity and resistance to the elements, even in the most challenging environments. When mounted, the WED21 slewing drive offers a solution that supports complex machinery with precision, efficiency, and long-lasting performance.

Features of Double Worm Slewing Drive WED21

The WED21 Double Worm Slewing Drive comes equipped with a range of features that elevate its performance, precision, and reliability. Below are the standout features that make the WED21 an ideal choice for demanding applications:

1. High Output Torque and Holding Torque
   The WED21 offers an impressive output torque of 48 kN·m, significantly higher than the WED17 series. The holding torque of 179.8 kN·m ensures that the system can maintain position even under substantial external forces. This increase in torque capacity makes the WED21 suitable for use in large-scale industrial machinery and heavy equipment that require substantial rotational force.

2. Enhanced Axial and Radial Load Capacity
   The WED21 is capable of handling greater axial and radial static loads compared to its predecessor, the WED17. With a static axial rating of 1598 kN and a static radial rating of 640 kN, the WED21 can support much heavier loads. This enhanced load capacity makes it suitable for applications such as cranes, excavators, and other heavy-duty machines that require high strength and stability.

3. Self-Locking Functionality
   One of the most critical features of the WED21 is its self-locking function, which ensures that the drive remains secure and prevents unwanted rotation when there is a loss of driving power. This safety mechanism is essential for applications that require high safety standards, such as heavy cranes, wind turbines, and offshore rigs.

4. Dual Worm Drive for Increased Efficiency
   The WED21 employs a double worm gear configuration, which results in increased efficiency and power transmission. This dual worm drive design not only enhances torque output but also improves overall system performance by reducing the load on each individual worm, making the system more durable and efficient.

5. Sealed Protective Housing
   Like other high-performance slewing drives, the WED21 is encased in a sealed protective housing that shields the internal components from dust, moisture, and other contaminants. This sealed design ensures the drive can withstand harsh environments, including those exposed to high humidity, dust, and extreme temperatures. The WED21 is suitable for both indoor and outdoor use, making it versatile for various industrial applications.

6. High Precision and Tracking Accuracy
   The WED21 features a tracking precision of ≤0.1°, ensuring high accuracy in rotational positioning. This is particularly crucial in applications that require precise movement, such as wind turbine rotation, telescope platforms, and positioning systems in aerospace or defense applications.

7. Dual Row Ball Bearing for Increased Load Capacity
   The WED21 is equipped with a dual-row ball bearing (eight-point contact ball series), which improves its axial and radial load capacity. This bearing type ensures that the slewing drive can handle significant load variations while maintaining stable operation, especially in heavy machinery where both axial and radial forces are common.

8. Optimized Gear Ratio
   The WED21 offers a gear ratio of 90:1, providing a balanced combination of high torque and speed. This gear ratio is optimized for heavy-duty applications, delivering the right amount of torque without compromising the speed of the system. The 90:1 ratio is suitable for applications that require a slower, more controlled movement, such as cranes and turntables.

9. Heavy-Duty Construction
   Weighing 195 kg, the WED21 is a heavy-duty slewing drive designed to withstand intense forces. The substantial weight reflects its robust construction, designed to ensure durability and reliability even under the most demanding conditions.

Applications of Double Worm Slewing Drive WED21

The WED21 Double Worm Slewing Drive is designed for use in a variety of demanding applications where high torque, high load-bearing capacity, and precise rotational movement are required. Below are the key industries and applications where the WED21 is commonly used:

1. Heavy Machinery and Equipment
   The WED21 is ideal for large-scale construction and mining equipment such as cranes, excavators, and loaders. These machines often require high torque to lift and move heavy loads, and the WED21 slewing drive provides the necessary power to perform these tasks efficiently. The slewing drive's enhanced axial and radial load capacity makes it suitable for the heavy-duty requirements of these machines.

2. Renewable Energy – Wind Turbines
   In the renewable energy sector, the WED21 is used in wind turbine systems, where it helps to rotate the turbine nacelle to optimize its exposure to the wind. The slewing drive's self-locking feature ensures that the turbine remains stationary when not in operation, preventing unwanted movement in high-wind conditions.

3. Marine Applications
   The WED21 is suitable for marine applications, such as positioning and rotating cranes on ships, offshore drilling platforms, and winches. Its sealed design makes it resistant to saltwater corrosion and other harsh marine conditions. Additionally, the WED21’s high torque output makes it suitable for heavy marine lifting equipment.

4. Aerospace and Defense
   In aerospace and defense applications, the WED21 is used in systems that require precise rotation, such as radar systems, antenna positioning, and satellite dishes. The slewing drive’s high precision and reliability are critical for systems that must operate without fail in sensitive and high-stakes environments.

5. Industrial Automation
   The WED21 is often found in industrial automation systems that require reliable rotational movement, such as robotic arms, conveyor systems, and automated assembly lines. Its ability to handle heavy loads and provide smooth, controlled movement makes it a valuable component in automated manufacturing.

6. Material Handling
   In the material handling industry, the WED21 slewing drive is used in turntables and rotating platforms that manage large, heavy items. The slewing drive’s ability to support axial, radial, and tilting forces ensures that material handling equipment operates efficiently and safely, even under heavy loads.

7. Offshore and Oil & Gas
   The WED21 is well-suited for offshore drilling rigs and other oil and gas equipment that require high torque and precise movement.
